VMWare ESX = the most mature and established hypervisor platform Xen Server= newer hypervisor, based on a better technical foundation, catching up with VMware, not as "Enterprise" able MS Hyper-V= new kid on the block, based on XEN technology, has muscle of MS behind it, it is free, MS is targeting the management of virtual machines as their new market opportunity and pulling out all stops to get there first and knock VMWare out Steve Greenberg Thin Client Computing 34522 N.

All - Let me preface this by saying, I run a relatively small shop with a single CPS 4.0 farm and single WI/CSG deployment. Now, Management wants to get involved with server virtualization. They are heading towards the direction of VMware but i do know that Citrix is in the virtualization space as well, but i don't know to what capacity. I, personally, have always thought that VMware would be the route to take to get server's and client's virtualized -- does citrix have something to compete with vmware ESX/Workstation ? in other words, what exactly is citrix doing with regards to virtualization ?
